Graphene composite leads to breakthrough in rechargeable battery applications
A Kansas State University engineer has made a breakthrough in rechargeable battery applications.Gurpreet Singh, assistant professor of mechanical and nuclear engineering, and his student researchers are the first to demonstrate that a composite paper -- made of interleaved molybdenum disulfide and graphene nanosheets -- can be both an active material to efficiently store sodium atoms and a flexible current collector. The newly developed composite paper can be used as a negative electrode in sodium-ion batteries.The bottom image shows a self-standing molybdenum disulfide/graphene composite paper electrode and the top image highlights its layered structure.
